Place value - Counting in 3s - Presentation

Mastering the concept of place value and number sequences is essential in mathematics, and counting in threes is a fundamental skill that reinforces this understanding. In a series of engaging activities, students are prompted to identify patterns and continue sequences by counting in increments of three. The first activity presents a number line with certain numbers circled, challenging the students to discern the pattern of numbers increasing by threes. This exercise encourages observation and pattern recognition as students continue the sequence, reinforcing their grasp of place value and number progression.

Further activities require students to complete number sequences by filling in missing numbers, ensuring they understand the concept of counting in threes. For example, they are given a sequence with gaps and must determine the correct numbers that fit the pattern. In a practical application of this skill, students calculate how many football cards Zach will have after collecting three each day for six days. Additionally, reasoning exercises challenge students to evaluate statements about counting in threes and to explore what new patterns emerge when numbers from different sequences are combined. These activities not only test students' ability to count in threes but also enhance their reasoning and problem-solving skills.
